so it seems having some low oil pressure issues with my lmm. I know the lmm is known for having low oil pressure sometimes but is there anything you can do to fix it? the low oil pressure warning light keeps coming up every time I tow something. It did it twice today when I was towing about 5k lbs at about 65mph and it getting annoying. I just changed the oil about 200 miles ago so I know the oil is in good shape and the level is normal.

My question is it just the sender itself reading low? Or is it because its 90*F outside right now? Or does the truck need a bigger oil cooler? Or maybe all 3? I never have this problem with my lly has 3x the oil pressure my lmm does. Anyone else having this problem?

No warranty? What weight oil? I would also check it with a manual gauge, maybe the sending unit is out of whack.

Im pretty sure the warranty was voided when I took the DPF off and tuned the truck. The oil is 15W40 rotella. Im in the process of getting a manual gauge to check and see if the sending unit is reading wrong.

I should have just bought another LLY instead of this LMM. Its always somthing with this truck

why would you have to log it? The cluster shows exactly what the ECM is seeing on the sensor....

so basically, what you're gonna log is exactly what the oil pressure gauge is gonna say.
